I was talking about the seams of the tape or fiberglass. If you over lap it it will be more built up and you would have a high spot thus more sanding. Thanks again for all the help and sorry if I am asking to many questions.

You can lay the cloth end to end and it will be ok. If it were a power or sail boat, you'd need to overlap. Make sure the "butting ends" of the tape are trimmed clean and fit together as neatly and closely as possible. Minimal gap. You'll want to wet the area where the ends butt together first and work your way out. The tape will move a little bit as you wet it out so check on it before you walk away.
